Fingerprint scanning on a smartphone can be used not only for the in-device security, but also for the security and verification of a whole lot of other services. So far, Apple hasn’t opened up the use of its fingerprint sensor to other developers.

But Samsung is making available such access from the get-go. While Galaxy S5 is due to hit the shelves today, PayPal is debuting its own integration along with it. Users can hit the fingerprint sensor on Galaxy S5 to log into their PayPal accounts and later verify their transactions.

It remains to be seen whether other players in the online payments industry make a similar move by forging partnerships with Samsung. Or perhaps, most will sit back and see how the Gear 2 sales play out and only then make the decision. Plus, there’s also the possibility of Apple opening up its biometrics to companies like PayPal in the coming months.
